Air-cooled or dry-type transformers do not have a core. The two windings are facing each other and are surrounded by air. In large transformers, the enclosure or case is ventilated to allow air to flow and cool the windings. Because they are environmentally safe, they can be used indoors of houses or buildings.

A simple rubber washer and metal disk or dish secures the transformer to the chassis or board. There is usually a through-hole in the middle of the disk that allows for a screw to hold the transformer down.

Pad-mounted transformers are mounted on the ground, sitting on a concrete (or other material) pad. They are normally step-down transformers used in power distribution systems to step down the voltage from the high voltage terminals of an underground distribution system to the low voltage of the end user’s needs.

Any of a variety of signal transformers mounted on PCBs. They can either be surface-mounted or through-hole configurations, using the soldering method to hold the transformers. PC-mount transformers offer a small footprint for the design engineer looking to measure sensor current or voltage on a computer board. Some applications for PC or PCB transformers include sensing current overload, ground fault detection, metering, isolated current feed-back signal in switch mode power supplies, motor current load / overload, lighting, switch controls, ultra-sound current, high resolution sonar current, and isolated bi-directional current sensor with full wave bridge.

User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.

The maximum primary voltage rating is the input voltage range of the transformer. Transformers for use with several nominal voltages need more than one primary winding. Enter the maximum voltage required for the application. Matching products will list all primary voltages available in addition to the maximum specified.

User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

The maximum secondary voltage rating is the output voltage range of the transformer. A transformer may provide more than one secondary voltage. Enter the maximum voltage required for the application. The matching products will list all secondary voltages available in addition to the maximum specified.

Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive that requires all manufacturers of electronic and electrical equipment sold in Europe to demonstrate that their products contain only minimal levels of the following hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl and polybrominated diphenyl ether. RoHS became effective on July 1, 2006.

The Germany-based VDE Testing & Certification Institute is accredited on a national and international level in the area of testing electrotechnical products. Testing is conducted for safety, electromagnetic compatibility, and other characteristics.

Waste Electrical and Electronics Equipment (WEE) is a European Union (EU) Directive that aims to encourage the reuse, recycling, and recovery of electrical and electronic equipment, and to improve the environmental impact and performance of this equipment. WEEE establishes the requirements and criteria for the collection, treatment, recycling, and recovery of this equipment. It makes producers responsible for financing these activities, and retailers and distributors must provide means for consumers to return used or obsolete equipment without charge.

Any other agency that that tests or certifies electrical, electronic, or electrotechnical products.
